Abstract

The utility model provides a stress reducing structure of a catalyst basket. The section of a supporting circular ring of a catalyst net is in an S-shaped structure, so that thermal stress generated by catalysis reaction can be greatly reduced; furthermore, the side wall of the catalyst basket is in an inverted U-shaped structure, so that the influence, which is caused by the thermal stress, on the catalyst basket is further alleviated; and therefore, the stress resistance of the catalyst basket can be greatly implemented, the service life of the catalyst basket is greatly prolonged, and the cost of catalytic production is greatly reduced; the stress reducing structure has extremely high economical benefits.

Description

A kind of catalyst basket subtract stress structure

Technical field

The utility model relates to a kind of stress structure that subtracts of catalyst basket, belongs to technical field of chemical.

Background technology

In the reaction of catalyst furnace, more than temperature generally reaches 800 degree, at so high temperature, the catalyst basket of bearing catalyst and catalysis net tends to bear very large thermal stress, cause support section and the sidewall of the catalysis net of catalytic basket to produce even fracture of distortion, have to change, increased production cost.And the support section of the catalysis net of existing catalytic basket and sidewall adopt linear pattern result mostly, can not effectively eliminate the thermal stress that catalytic reaction produces, cause shortening the service life of catalytic basket, make production cost increase.Therefore, be necessary to design a kind of catalytic basket that can better reduce catalytic reaction thermal stress and subtract stress structure.

Utility model content

The utility model relates to a kind of stress structure that subtracts of catalyst basket, belongs to catalytic unit field.

For the deficiency of above-mentioned technology, the utility model provides a kind of stress structure that subtracts of a kind of catalyst basket that can significantly reduce catalytic reaction thermal stress.

The utility model is to adopt following technical measures to realize utility model object:

Catalyst basket subtract a stress structure, it is characterized in that: the support ring cross-section of catalyst gauze is S shape structure.

Preferred:

The sidewall cross section of the catalytic basket being connected with catalyst furnace housing is inverted U-shaped, can realize self-absorbing thermal expansion. guarantee the optimum state of catalyst basket in level;

The top material of described inverted U-shaped is steel pipe;

In described inverted U-shaped, be provided with the steel plate annulus that is welded in inwall;

In described inverted U-shaped and catalyst furnace housing junction, be provided with the steel plate that is welded in junction inwall;

Beneficial effect: because the support ring cross-section of catalyst gauze has adopted S shape structure, can reduce significantly the thermal stress that catalytic reaction produces, in addition at catalytic basket sidewall, adopt inverted U-shaped, reduced further the impact of thermal stress on catalytic basket, the anti-stress ability of catalytic basket can be greatly provided, greatly increase the service life of catalytic basket, reduced significantly the cost of catalytic production, there is very large economic benefit.

Accompanying drawing explanation

Fig. 1 is the structural representation that subtracts stress structure of catalyst basket, the Z partial view that Fig. 2 is Fig. 1.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, illustrate embodiment of the present utility model:

Catalyst basket subtract a stress structure, it is characterized in that: support annulus 1 cross section of catalyst gauze 6 is S shape structure, the place that very easily produces thermal stress at catalytic basket, adopts said structure, can greatly reduce the impact of thermal stress on catalytic basket.

Preferably, the sidewall cross section of the catalytic basket being connected with catalyst furnace housing 5 is inverted U-shaped 2, can realize self-absorbing thermal expansion. guarantee the optimum state of catalyst basket in level.

Preferably, the top material of described inverted U-shaped 2 is steel pipe, and steel pipe is stronger than the anti-stress ability of solid steel.

Preferably, in described inverted U-shaped, be provided with the steel plate annulus that is welded in inwall, increase the intensity of distortion junction, put forward high resistance to stress ability.

Preferably, in described inverted U-shaped and catalyst furnace housing junction, be provided with the steel plate that is welded in junction inwall, increase the bonding strength of sidewall and burner housing, put forward high resistance to stress ability.
